I am trying to do some integration tests run against a WAR that has been already given to me - created out of an independent maven build. My goal is to deploy the WAR into an embedded tomcat 7 server, and execute a few tests by invoking REST URLs against the deployed application. However, I get error during deployment of the WAR file (I have deployed this WAR successfully into a Tomcat 7.0.55 server). Here is the error - any help will be greatly appreciated.

SEVERE: The web application [/cca] created a ThreadLocal with key of type [com.sun.xml.bind.v2.ClassFactory$1] (value [com.sun.xml.bind.v2.ClassFactory$1@3bd5401b]) and a value of type [java.util.WeakHashMap] (value [{class javax.xml.bind.annotation.W3CDomHandler=java.lang.ref.WeakReference@2ad4a8e3}]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
